Looks different than what John was carrying. That UB design looks real similar to what I designed for that contest physical flight had on the boards a while back.

The ergo2 (I'm not calling it this, it was embroidered on the bag) has the vertical storage with a open putter pocket on the front. It looked to hold about 4-5 discs in that pocket. The side pockets were the same design as the ergo just bigger. I would think it could hold a good bit more than a cellphone and wallet. The drink holders were more toward the front of the bag. Probably to help balance it more. The ergo2 proto did not have the mahal like side pockets that the UB has.
